So, forvive me for being too critical, but they update the charts every year...why wouldn't they compensate for the cam technology??

Wwag, 28.5-29 draw with a 27.75 arrow @ 70lbs

No Frank, I think I get it.

I mean I loved the way the 2512's shot, but if I hit a gnat in flight on the way down they'd bend and I'm pretty hard on equipment anyway.

So an arrow with thinner overall diameter but thicker walls will actually be less stiff or have less spine...but it would be more durable??
